AUXILIARYY FLUID FLOW SYSTEM DEBRIS FILTER

摘要

The present disclosure relates generally to a fluid flow system having a debris filter media therein to remove debris from a fluid flowing therein. A valve is provided to periodically change the flow direction of fluid within the system so that debris trapped on the debris filter media is scrubbed off by the flow of fluid across a face of the debris filter media.

主权项

1. A fluid flow system, comprising:
a main fluid system passage; an auxiliary fluid supply passage; an auxiliary fluid system passage; a valve passage operatively fluidically coupling the main fluid system passage, the auxiliary fluid supply passage, and the auxiliary fluid system passage; a valve disposed in the valve passage, wherein the valve operable to be placed into:
a first position in which fluid flowing in the auxiliary fluid supply passage is not permitted to flow to the main fluid system passage and is permitted to flow to the auxiliary fluid system passage; anda second position in which fluid flowing in the auxiliary fluid supply passage is permitted to flow to the main fluid system passage and is not permitted to flow to the auxiliary fluid system passage; and debris filter media disposed within the valve passage between the auxiliary fluid supply passage and the auxiliary fluid system passage.
